Q: What do 1st, 2nd and 3rd mean?

A: These ordinal numbers denote position in an ordered sequence. For instance, "1st" represents first place or position; "2nd" represents second place or position; and so on.

Q: What's the difference between ∑ (capital sigma) and Σ (uppercase Greek letter Sigma)?

A: Both are summation symbols but they differ slightly in terms of context in which they are used. Capital sigma (∑) is often used for finite sequences while uppercase Greek letter Sigma(Σ) usually denotes a sum over an infinite set or sequence.

Q: What does ≡ mean?

A: This triplet equals sign is known as a "congruent to" symbol meaning that two things are congruent(modulo). It indicates that two expressions have equivalent values under certain conditions such as with respect to modular arithmetic(usually within fields like geometry).

Q.Why do mathematicians use × instead of * for multiplication?

A.The cross(X) in mathematics means 'times' just like it does when written down(for example $$$$ x=16). The asterisk(*) symbol commonly signifies more general operations such as indicating multiplication when working with programming languages since multiply operations can't be denoted using its ASCII codes because it reserves them(otherwise what would you get if you tried ∗ ? ;))?

A.Within mathematics,% refers to percent (out of one hundred).(For example, expressing 𝑃(𝐴)=25% means the probability of A occurring is 1/4, which can also be written as a fraction)

Q. What’s the difference between ≤ and < symbols?

A.The symbol 'less than or equal to' (≤) means that the left-hand side is either less than or equal to the right-hand side value while '<'(less than) simply indicates merely only strictly less.

Q: Why do mathematicians use Greek letters for variables?

A: The main reason why Greek letters are used in mathematics is not just because they look different but also for clarity and simplicity when referring to particular mathematical concepts. Some disciplines use them more often such as physics where several frequently important parameters such as λ,were historically associated with specific components of electromagnetic radiation waves.
